Dissecting Pelagic Fish

What are pelagic fish? Pelagic fishes are those that live in the pelagic zone. In other words, it's fish that lives in the open sea. It was interesting since we were given reef fishes to compare with those of the pelagic ones. The main difference between the two is that reef fish live in coral reefs and are closer to the shore. In this week's lab, we were to identify the external and internal features of a fish. Afterward, we were to compare the difference between the organs and systems of the pelagic and reef fish.

Our canoe (Dinanche) started right away. After identifying the external organs, we went straight to cutting open the fish. We got to identify the organs that help a fish survive like a "gas bladder". After what seemed to be forever, the class began to clean up the now dismembered fishes. The highlight out of all this was the professors' fish finding - he found worms hiding in the meat of a tuna. It looked interesting yet extremely disturbing up close. 'Til next time!

Things we can't see

There are some things the human eye simply cannot see. This week for Marine Biology, our class got to utilize two different microscopes. The professor collected some marine species to observe; some animals and planktons. It was great because all groups got to see certain mutations their bodies adapted in order to survive within their respective environment. We got to take turns to observe corals, sea spiders, snails, clams, and seaweed. It all looked a bit out of this world as if I borrowed glasses from someone who was almost blind. The sea spider creeped me out the most due to its multiple legs. I think that the most important part of the lab was seeing the plankton roaming around the water. To think that a colossal amount of animals rely on this tiny species to survive boggles my mind up to now. After all, it is what feeds almost the whole food chain, one way or another. So in that case, hurray for the tiny things that swim around in our oceans! You guys rock!

EdPuzzle

For ED271, we were introduced to a new software called EdPuzzle. What is EdPuzzle you ask? Basically it's an interactive video that allows teachers to teach outside of a classroom. This includes, but is not limited to: asking questions, customizing a video to suit the class, and adding audio notes along the way. It's a great tool to have around as a way to keep track of how students perform outside of the classroom. This is most beneficial to online students, teachers who want students to learn the topic beforehand or teachers testing students after the lesson.  The topic I chose for EdPuzzle were the three states of matter. Since Crash Course is a popular youtube channel for middle, high school, and college students, I thought it would be nice to explore Crash Course within the elementary curriculum as well. After condensing the video to the length I thought students would reasonably watch, I added questions and audio notes along the video to ensure they understand it. THE ...

Under the weather

It's official. I am siiiiiiiiiiiiiiick. I was unable to attend lab this week. It was going to be at Ypao Beach where they were to feed the fish, but since I still have a severe cold, I decided it was best to stay away from the beach until I make a full recovery. For now, I must make do with nothing but soup and long hot showers to clear away this nasty cold from my system. Be gone, blasted cold!
